Problems solved by technology

[0004] Since the axial forces required to break the cage are usually high, it cannot be ruled out that the shafts do not move into each other but bend
In addition, it is not excluded that the cage parts can jam and thereby substantially prevent the pushing movement without force
Consequently, the desired results in the prior art are sometimes not achieved, but instead there is the risk that the propeller shaft bends uncontrollably and injures the occupants of the vehicle at this time

Embodiment Construction

[0035] The propeller shaft 1 shown in FIG. 1 is designed as a longitudinal propeller shaft of a motor vehicle and comprises two partial shafts 2 and 3 carrying connecting pieces 4 , 5 at their free ends. The connecting piece is here designed as a rubber-elastic disc joint (Gummigelenkscheibe), although as in the case of the prior art, or as described in DE 10237172B3 or DE 10032853C2, it can also be fastened here on the partial shafts 2 and 3 Transmission joint.

[0036] The two partial shafts 2 and 3 are connected to each other approximately in the middle of the gear mechanism 1 via a drive joint 8 , which is shown in different sectional views in FIGS. 2 to 9 . Furthermore, FIG. 1 shows that the left partial axle can be fastened to the underbody of the motor vehicle via an intermediate bearing 6 and a holder 7 arranged thereon.

[0037] Because the transmission joint 8 in the middle is designed to be detachable according to the present invention, this transmission structure ...

Abstract

The invention relates to a drive joint (8) for permitting a non-rotationally and axially fixed connection between a first and second shaft sub-section (2, 3), said connection allowing a limited angular displacement.

Description

technical field [0001] The invention relates to a telescopic drive joint / universal joint (Antriebgelenk) for non-relative coupling between first and second partial shafts of a drive shaft, for example a longitudinal shaft of a motor vehicle. Connections that are rotationally and axially fixed but allow limited angular movement, wherein the drive joint has an inner joint (inner hub) and an outer joint (outer hub) and as other joints A component is provided between said inner and outer parts in a torque transfer structure - such as a ball - and a structure guiding the component - such as a cage. Background technique [0002] A drive shaft is known from DE 19943880 C1 with two partial shafts connected to one another via an approximately centrally arranged drive joint. The cage of such a drive joint has a predetermined breaking point, which is designed so that a large axial force acting on a part of the shaft, which can occur, for example, in an accident, can destroy the cage a...
